Pasternack Enterprises has announced a series of 5 Bit, 8 Bit and 10 Bit broadband PIN diode digital step attenuators with performance up to 40 GHz (depending on the configuration). Programmable and variable step attenuators are commonly used in electronic warfare, military and space communication systems, radar and test and measurement applications.
Pasternack’s new digital step attenuators come in 30 dB and 60 dB attenuation configurations and have an attenuation step resolution of 0.25 dB to 1 dB. The attenuators offer excellent attenuation accuracy and flatness all the way up to 40 GHz. Insertion loss ranges from 4 dB to 8 dB and P1dB (power) ranges from 10 to 20 dBm. These new variable attenuators meet MIL-STD-202F standards for shock, vibration, altitude, humidity and temperature and are constructed using a durable, but slim line housing, measuring only 0.5” thick.
The new high precision PIN diode digital attenuators from Pasternack offer fast and reliable switch speeds and high linearity. The lower frequency 0.03 to 18 GHz digital step attenuators are equipped with female SMA connectors, while the high frequency units that go up to 40 GHz use female 2.4 mm connectors. The power control connector for each unit is a 15 PIN Micro-D-Female connector. The latest addition of PIN diode digital step attenuators provide customers an off-the-shelf solution previously not available for these types of high reliability products where long lead times can exceed 8-12 weeks.
